ALFRED BERNEY, OF BOSTON, MASSACHUSETTS, ASSIGNOR TO THE GLOBE COMPANY,OF HARTFORD, CONNECTICUT. v

SPARK-CONSUMER.

SPECIFICATION forming part of Letters Patent No. 248,010, dated October11, 1881.

Application filed March 12, 1881. (No inodel.) Y

To all whom it may concern:

Be it known that I, ALFRED BERNEY, a citizen of the United States,residing at the city of Boston, in the county of Suffolk and State ofMassachusetts, have invented certain new and useful Improvements inSpark-Consumers;

and I dohereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to letters or figures of referencemarked thereon, which form a part of this specification.

My invention relates to spark arresters and consumers in whichthesparks, einders, &c., are arrested and deflected and returned to thefurnace by return-flues, to be there consumed and assist in thegeneration of steam; and the object in this instance is to dispense withthe ordinary flaring or enlarged stack and substitutin g therefor thestraight stack.

Theinvention consists, principally, in arranging in the saddle of thestack a truncated cone of wire-netting or perforated sheet metalconnected by a pipe over the exhaust-tips to the bottom of thesmoke-arch and attached to a ring at its upper and lower ends. Thesparks, cinders, &c., are deflected into thev hollow saddle, and fromthence through a connecting-pipe and returnrflues into the furnace, allof which will be more fully described hereinafter, reference being hadto the letters of reference in the accompanying drawings, in whichFigure 1 is a longitudinal vertical section of a locomotive-boilerembodying my invention. Fig. 2 is a "ertical cross-section on line a x.

In the drawings, A represents an ordinary locomotive-boiler, having-theusual furnace, B, tubes or flues and smoke-arch D.

Above the smoke-arch is arranged the hollow saddle E, provided withinclined guides, by which the sparks, cinders, &c., are guided into theconnecting-pipes F, which communicate with the return-flues G, andthrough them with the furnace B. In the smoke-arch are arranged theordinary exhaust-tips, g, over which is attached a conical perforatedpipe, H, of wire-gauze or perforated sheet metal. This pipe H is held inposition at its upper end by a ring, I, by which'it is secured to thesaddle,

and at its lower end bya ring, K, to the smokearch. By this pipe theexhaust-steam can pass freely into the atmosphere, and prevent anyback-pressure on the pistonsof the engines, and the unconsumed gases canfreely escape. The sparks, cinders, 8m, are, however, drawn by theexhaust blast-pipes upward through the lift-pipe L, and are deflected bythe curved part 1 of the saddle into the annular space a of the saidsaddle, and thence by means of the inclined guides at into theconnecting-pipe F, and through the force of the steam-jet a are carriedthrough the return-flues G into the furnace B. The usual lift or blastpipe, L, surrounds the pipe H, and through the space formed betweenthese two pipes the sparks, cinders, 850., are forced into the saddle.

The steam-jet pipe is provided with a valve, and may be connected to theordinary steam- 7o pipes, M, leading to the'cylinders or to the boiler;or, ifdesired, a branch pipe, b, maybe used, andconnected with theexhaust-tips, and by it the sparks, einders, &c., forced through thereturn-flues into the furnace.

The saddle is provided with a curved lip, l, and an annular flaringmouth, (1, by which the sparks are guided or deflected into the annu-'lar space a and onto the inclined guides m. The curved lip lis generallycast separate from the saddle and bolted onto it. A re-enforce should becast and bolted'on at O, as shown in Fig. 2. It will save the curve Ifrom being worn out too fast.

Having thus described rnyinvention, what I claim, and desire to secureby Letters Patent,

1. The combination of a conical perforated pipe, H, connected to thebottom of the smokearch, and saddle E, in the manner and for the 0purpose herein specified.

2. In a spark-arrester, the combination of a conical perforated pipe, H,with the hollow saddle E, connectingpipes F, and return-flues G,arranged substantially as set forth.

3. In a spark arrester and consumer, the combination of the conicalperforated pipe H, hollow saddle E, provided with inclined guides,

scribed, provided with a curved lip, Z, and an annular flaring mouth,(1, arranged substantially as shown and specified.

In testimony whereof I afllx my signature in with the lift-pipe L,exhaust-tips G, connectin g-pipes F, and return-fines, all arrangedsubstantially as shown and specified.

4. Inaspark arrester and consumer, the com- ALFRED BERNEY.
